Yeah Nadal as a clay courter definitely. I was reading up on Federer, and his consistency was ridiculous. It's just unbelievable, something like 30 straight semifinal appearances and ranked #1 for the most ever. In my mind that one ups him on so many people. He never got hurt, or if he did you never knew, and he just played at a high level everywhere forever. I wish Federer was younger so his prime lined up with Nadal's, Djoker's, and Murray's. (And of course away from Roddick's)
